摘　　要：目的研究不同基体烧成温度对氧化铝-氧化锆纳米复合渗透陶瓷性能的影响。方法采用1 250、1 300、1 350℃的基体烧成温度制备氧化铝-氧化锆纳米复合渗透陶瓷,测试其基体堆积密度和线收缩率;扫描电镜观察其显微结构。结果基体烧成温度采用1 250、1 300、1 350℃所得复合渗透陶瓷的线收缩率分别为(2.16±0.51)‰、(2.92±0.97)‰、(3.76±0.70)‰,差异有统计学意义(P<0.05);其基本堆积密度分别为76.94%、78.66%、80.16%,基体堆积密度随温度增加逐渐增大,但差异无统计学意义(P>0.05)。结论 1 250℃是较合适的氧化铝-氧化锆纳米复合渗透陶瓷基体烧成温度。Objective To investigate the influence of different matrix sintering temperature on the performance of alumina-zirconia nano-composite infiltrated ceramic.Methods The alumina-zirconia nano-composite infiltrated ceramic was prepared by different matrix sintering temperature（1 250,1 300,1 350 ℃）.The matrix stacking density and linear shrinkage were measured.The microstructure was observed by scanning electron microscope.Results The linear shrinkage rates of composite infiltrated ceramic prepared by matrix sintering temperature 1 250,1 300 and 1 350 ℃ were（2.16±0.51） ‰,（2.92±0.97） ‰,（3.76±0.70）‰,respectively,with statistical difference（P0.05）.Conclusion 1 250 ℃ is the relatively suitable matrix sintering temperature for alumina-zirconia nano-composite infiltrated ceramic.
